SPECIFICATION forming part of Letters Patent No. 268,425, dated December 5, 1882.

' Application filed May 6, 1882. (No inodel.)

To all whom it may concern Be it known that I, JosEPH O. MILLER, of

Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Soda-Water Draftlubes, of which the following is a specification. v

The object of my invention is to provide a cheap, simple, convenient, and durable draft- 1o tube for soda-water apparatus, so as to draw first a large and then a small or fine stream by the rotation of a single hand-wheel to open and close the valves, instead of actuating two hand-wheels, as heretofore, in order to accomplish the desired result; and it consists in the construction, combination, and arrangement of the valves and other parts of the drafttube, as hereinafter more fully described, and

' set forth in the claims.

2 Figure lrepresents a vertical central section of a draft-tube and its valves, embodying my invention. Fig. 2 is a similar view with a changed position of the valves, so as to draw a fine stream.-

A represents the spheroidal valve-case provided with the soda-inlet passage B, curved or deflected upward and opening into the valve-seat O, beneath the rubber or other suitable valve or packing-ring, D, upon the top 0, of which rests the metal washer E, which receives pressure from or has a bearing against the shoulder F, formed upon the vertical spindle G of the hand-wheel H, which is provided with a screw-thread engaging with an inter- 5 nal thread provided within the screw-valve case T, which is provided with an external screw-thread engaging within, a corresponding screw-thread formed internally within the cavity formed within the upper portion of the spherical valve-case A. It will be seen that it'the hand-wheel be turned sufficiently the said valve will be opened and closed, and that when turned upward a short distance the pressure of the soda or other mineral wa- 5 ter employed in the fountain will force the said valve D upward from the seat 0, so as to permit the discharge of a full or large stream of the same downward through the outlet-passage and nozzle Z, as usual, and by which operation nearly the desired quantity of soda is quickly drawn into the glass. Now, in order to raise a foam upon and within the soda thus drawn, .it must be completed by forcing a very small stream of soda therein, under increased pressure, and I accomplish this desired result in a very simple manner by providing a small tube or quill, L, secured at its upper'end to the lower end of the said vertical spindle H, and providing the same with a hole or a series of horizontal holes, 8, 6o entering into the same or into its interior opening or longitudinal passage, and provide its lower or middle portion with a screw-, thread, it, fitted with an adjusting-nut, J, washer K, and rubber or other suitable packing-valve, N, which may be drawn upward against the valve-seat R by turning the handwheel H in the same direction, so as to draw the said tube or quill L upward, and thereby close the main outlet outside of'said quill 7o through-the said valve-seat R by drawing or carrying the said rubber packing N upward against its seat R, and thereby force the soda through the said holes or perforations s, and thence downward through the said small tube 7 or quill L into the glass, as shown in Fig. 2, such quill or tube L, being located centrally within and extending through the said nozzle Z, as clearly shown in the several figures of the drawings. By this construction only a single band wheel is employed to actuate both of the valves controlling the large stream and the small stream, thereby greatly reducin g the cost, and rendering the draft-tube very much more convenient and durable.

Having thus described my invention, what I claim is- 1. In a soda-water draft-tube, the combination and arrangement, with the valvestem having the main upper valve and provided 0 with the small interior tube, of the adjustable annular lower valve adapted to close the main annular outlet-passage by being drawn upward against its seat, and thereby force the discharge through the small tube, substantially 5 as shown and described, as and for the purposes set forth.

2. In a soda-water draft-tube, the combination, with the valve-stem having the main valve and provided with the small perforated 10o interior tube,ofthe lower annular valve adapted to close the main outlet-passage and thereby force the discharge throughthe said small interior tube, substantially as described, as and for the purposes set forth.
